Point of Sale Verification for Payment Transactions Exceeding Limits
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Consumers face difficulties in making emergency or special occasion purchases that exceed their established account limitations, as existing systems often require manual adjustments through mobile devices and may be time-consuming or inaccessible without a device or network connection.
Innovation Solution
A system and method for consumer verification of payment transactions that exceed account limitations, involving a processing server that transmits questions to a point of sale device for consumer confirmation, allowing transactions to proceed without modifying account controls, using existing payment networks and devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If account controls or limitations are enforced to help consumers budget and monitor spending, then spending control is improved, but the ability to make emergency or special occasion purchases is restricted
Solution Approach 1:
The system pre-establishes account controls and limitations to help consumers budget and monitor spending. When a transaction exceeds these pre-set limits, the system automatically triggers a verification process that allows the consumer to temporarily override the control for emergency or special occasion purchases, then automatically restores the original control settings afterward.
Solution Approach 2:
The account control system dynamically adjusts between enforced limitations and temporary overrides. The system transitions from a static control state to a dynamic verification state when limits are exceeded, allowing flexible response to different transaction scenarios while maintaining overall spending control integrity.
2Adaptability or versatility
If consumers manually adjust account controls through mobile devices to authorize exceeding transactions, then transaction authorization flexibility is improved, but the process becomes time-consuming and may be unavailable without device or network access
Solution Approach 1:
The patent introduces an intermediary verification system that acts as a mediator between the point of sale device and the account control system. When a transaction exceeds account limits, the point of sale device automatically communicates with the verification system, which then contacts the consumer through alternative means (such as SMS or automated calls) to obtain authorization. This intermediary process eliminates the need for the consumer to manually access their mobile device or application, significantly reducing the time required while maintaining security and flexibility.
3Reliability
If account controls are strictly enforced without verification mechanisms, then spending limitations are maintained, but legitimate emergency purchases are denied
Solution Approach 1:
The system implements a feedback mechanism where transactions that exceed account controls trigger an automatic verification process. The system provides real-time feedback to the consumer about the exceeded limit and seeks authorization. Based on the consumer's response, the system either denies or approves the transaction, then provides confirmation feedback. This feedback loop ensures account control integrity is maintained while allowing legitimate emergency purchases to proceed with proper verification.
Data Source
AI summary
A method for consumer verification of a payment transaction that exceeds previously established account limitations includes: storing account profiles, each including data related to a transaction account including a primary account number and transaction controls; receiving a transaction message related to a payment transaction including a specific primary account number, a point of sale identifier, and one or more additional data elements configured to store transaction details; identifying a specific account profile that includes the specific primary account number; determining that the payment transaction exceeds the account controls in the specific account profile based on the transaction details; transmitting question data for a plurality of questions to a point of sale associated with the point of sale identifier; receiving answer data from the point of sale; and transmitting the transaction message to a financial institution based on the answer data.
